So I have a customer that bought a sauna from somebody on OfferUp it comes with no manual and no indications anywhere of brand or model. This is a picture of the control panel on top and says the sauna requires 200-240v. Only issue is where cables terminate there is only 3 spots line, neutral, and ground. All specifically labeled that way. Wondering if that neutral spot is where I would land that second phase but don’t want to mess anything up in case I’m wrong. Hoping somebody else has seen something like this before. Thank you. Also has a 15 amp cord cap which doesn’t seem correct. Sauna currently works as is plugged into 15 amp circuit but will trip reset button on control panel once it reaches temp.
